论文摘要
政治Astroturfing和有组织的巨魔是在线恶意行为，具有重大的现实影响。研究这些现象的常见方法集中在广泛的运动上，而不是负责的小团体。为了揭示合作帐户的潜在网络，我们提出了一种新颖的时间窗口方法，仅依靠帐户互动和元数据。它检测到参与行为的账户组，这些行为协同执行了我们描述的不同基于目标的策略。我们的方法对两个具有地面真实数据的相关数据集进行了验证。
Political astroturfing and organised trolling are online malicious behaviours with significant real-world effects. Common approaches examining these phenomena focus on broad campaigns rather than the small groups responsible. To reveal latent networks of cooperating accounts, we propose a novel temporal window approach that relies on account interactions and metadata alone. It detects groups of accounts engaging in behaviours that, in concert, execute different goal-based strategies, which we describe. Our approach is validated against two relevant datasets with ground truth data.
